/**
 * The encoding is changed invalidating already scanned characters. When the
 * encoding is changed, as for example when encountering a &lt;META&gt; tag that
 * includes a charset directive in the content attribute that disagrees with the
 * encoding specified by the HTTP header (or the default encoding if none), the
 * parser retraces the bytes it has interpreted so far comparing the characters
 * produced under the new encoding. If the new characters differ from those it
 * has already yielded to the application, it throws this exception to indicate
 * that processing should be restarted under the new encoding. This exception is
 * the object thrown so that applications may distinguish between an encoding
 * change, which may be successfully cured by restarting the parse from the
 * beginning, from more serious errors.
 *
